6 Claims.

The invention relates to new and useful improvements in a bindersupporting means for sewing machines, and more particularly to a bindersupporting means for a machine of the type shown and described in thepatent granted Norman V. Christensen and Frederick F. Zeier, March 25,1930, No. 1,751,508.

An object of the invention is to provide a binder supporting meanswhereby the binder may be attached to the standard of the machine andsupported entirely free of the work support.

A further object of the invention is to provide a binder support of theabove type wherein the binder may be moved from operative to inoperativeposition and secured in either position.

A still further object of the invention is to provide a binder supportof the above type wherein the binder may be adjusted vertically andlaterally and longitudinally of the line of feed.

In the drawings which show by way of illustration one embodiment of theinvention Figure l is a front view of a machine having the inventionapplied thereto;

Fig. 2 is a plan view of the same with a portion of the needle headbroken away to show the position or" the binder relative to the worksupport;

Fig. 5 is a view partly in front elevation and partly in section of thesupporting bar and the carrying plate therefor on which the binder ismounted, the bar being shown in broken lines with the binder shifted toinoperative position, and

Fig. 6 is a section on the line 6-6 of Fig. 5.

In the Christensen and Zeier patent there is shown a machine of the typewherein there is a supporting standard carried by a supporting bed, andthis standard carries a projecting portion having bearings for theactuating shaft. The actuating shaft extends in the general direction ofthe line of feed. There is a work support mounted on the bed whichextends only a short distance beyond the line of feed and toward thestandard. The present invention has to do with the placing of a binderfor directing a binding strip about the edge portion of a fabric beingstitched, and a supporting means therefor which is mounted on thestandard. The supporting means includes a carrying plate which isattached to the standard and which is provided with a dovetailed recessin which a supporting bar slides.

A latch is provided for holding this bar in two difierent fixedpositions on the carrying plate. Attached to the bar is a bracket onwhich the binder is mounted. The binder is mounted on the bracket sothat it is adjustable bodily longitudinally of the feed. The bracket ismounted on the bar so that it is bodily adjustable in a directionlaterally of the line of feed, and the carrying plate is mounted on thestandard so that it is adjustable vertically. This provides for all thenecessary adjustments to insure the proper setting of the binderrelative to the work support, and it also provides a means which isentirely independent of the work support for supporting the binder.

Referring more in detail to the drawings, the machine to which thebinder is applied includes a supporting bed 1 carrying a standard 2. Thestandard has a laterally projecting portion 3 carrying bearings 4 and 5in which the actuating shaft 6 is mounted for rotation. At the forwardend of the standard is a needle bar 7 carrying a needle 8. Cooperatingwith the needle beneath the work support is a suitable stitch formingmechanism for forming a line of stitches. The shaft is connected to theneedle bar for reciprocating the same. Also mounted on the supportingbed 1 are supporting members, one of which is indicated-at 9, and thework support 10 is carried by these supporting members. The work supportit is provided with a throat plate 11. The needle passes through anopening 12 in the throat plate. The throat plate is provided with slotsthrough which the feed dog 13 operates. The line of feed is in thedirection of the arrow a in Fig. 2. It will be noted that the worksupport 10 extends for a short distance beyond the line of feed, thatis, to the right thereof toward the standard 2. The invention has to doparticularly with a binder and the supporting means therefor on amachine of the type described. The binder is indicated at 14. It is ofthe English binder type, and it is not thought that a detail descriptionthereof is necessary. It may be said that as the strip passes throughthe binder, its edges are folded on to one face of the strip, andthe'strip is then caused to pass in a direction at right angles to itsdirection of movement into the binder, and is inverted and thus placedabout the edge portion of a fabric with the edges of the binder stripinfolded. If a binding strip with a selvedge is used, then, of course,the binder will not necessarily be provided with means for folding theedges of the strip. The strip, however,

a recessed portion 15 in front of the needle opening 12. The binder 14extends into this recess. The throat plate is elevated slightly from theplane of the work support 10 so that the body fabric is raisedsufiiciently to permit the body fabric to pass through the end of thebinder and between the upper and lower portions of the binding strip asthey pass from the binder. The binder is mounted on a carrier 16 whichis attached t0 the standard 2 by screws, one of which is indicated at1'7. These screws pass through elongated slots 18 in the carrier plate,and these slots are so shaped as to permit the carrier plate to beraised and lowered or moved in a vertical direction and then secured inthe desired set position. The carrier plate 16 is provided with adove-tailed recess 19. A dove-tailed bar 20 is mounted in thisdove-tailed recess, and thus the bar is held on the carrier plate sothat it can move only in an endwise direction thereon. It will beunderstood, of course, that while a dove-tailed recess is used, otherways may be provided for mounting the supporting bar on the carrierplate for endwise movement thereon. Attached to this bar 20 is asupporting bracket 21. Said bracket 21 has elongated slots 22, 22therethrough, and screws 23, 23 passing through these slots firmly clampthe bracket to the bar. By loosening the screws, the bracket can beshifted in an endwise direction on the bar. This is for the purpose ofadjusting the position of the binder in a direction at right angles tothe line of feed or laterally thereof.

The bracket 21 has a right angle plate 24. Attached to this right angleplate 24 is a supporting plate 25 on which the binder 14 is mounted. Thesupporting plate 25 is provided with elongated slots 26. Screws 27 passthrough these slots and secure the supporting plate 25 to the bracket21. These elongated slots 26 extend in a direction substantiallyparallel with the line of feed and provide for adjustment of the bindertoward and from the needle. The supporting plate 25 has an upturnedportion 28 and the binder is attached to this upturned portion by screws29, 29. These screws 29 pass through elongated slots in the supportingmember 30 which is integral with the binder and supports the same. Thisprovides another means for shifting the binder vertically.

As a means for holding the bar 20 in set positions, a latch arrangementhas been provided which consists of a rod 31 mounted in a verticallyextending recess 32. The rod is provided with a handpiece 33 at theupper end thereof. The recess 32 terminates short of the lower end ofthe carrier so that the bottom end of the recess serves as an abutmentfor the spring 34 located in the recess. This spring at its upper endbears against the lower end of the rod. The rod is cut away at 35 for adistance so that when the rod is depressed the bar 20 is free to slideback and forth in the recess 19. The lower edge portion of the bar 20 isprovided with two notches 36 and 37. The portion 38 of the rod when inregister with the notch 36 will be raised by the spring into the notch.By pressing on the handpiece 33, the rod is depressed so as to releasethis portion 38 from the notch, and the bar can then be shifted untilthe portion 38 springs into the notch 37. When, the latch rod is in thenotch 3'7, the binder is in inoperative position and will be held frommovement. When the latch is in the notch 36, then the binder is inoperative position. When the latch. is depressed, the bar may becompletely removed from the'recess l9 and thus the binder taken from themachine. This provides a means for supporting the binder from thestandard of the machine. The cloth plate terminating as it does adjacentthe line of feed, does not afford a supporting means for the binderwhich must be so disposed as to lead the binding strip toward and aboutthe edge of the fabric being stitched. Furthermore, the supporting meansincludes a ture whereby the binder may be quickly shifted from one setposition to another, that is, from operative to inoperative or frominoperative to operative position. During the shifting of the binder,there is no adjustment of the supporting parts lost. All of thesupporting parts which provide for the adjustment of the binder in thedirection of f ed and laterally of the feed, are bodily shiftable to theinoperative position. Therefore, when the binder is returned to its setoperative position, the same adjustment is obtained as before moving itaway to inoperative position. Furthermore, the structure for supportingthe binder affords a ready means whereby the binder may be adjusted onthe bar which is shiftable on the carrier plate.

It is obvious that minor changes in the details of construction and thearrangement of the parts may be made without departing from the spiritof the invention as set forth in the appended claims.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is-
